Ganghwa Dolmen Sites (강화 고인돌)Korean dolmen is a type of grave of the Sinsa era, made of huge rocks, which is called one of the remnants of the prehistoric megalithic culture. The megalithic culture refers to a culture in which humans have a certain sense of purpose and make structures using natural stones or processed stones and use them as worship objects or graves. The pyramids of Egypt or the American continents, Stonehenge of England, Carnac Stones of France, and Moai of Easter Island are considered the relics of the megalithic culture.
Dolmens are found all over the world, but most of all they are found in Northeast Asia. Among these countries, so many dolmens were found in Korea so that it can be called “the kingdom of dolmens”. Up to now, about 30,000 dolmens have been found in South Korea and nearly 15,000 dolmens in North Korea, representing more than 40 percent of the world’s dolmens.
Among the 30,000 high dolmens discovered near Bugeun-ri in Ganghwa, there are dolmens, which are known for not only height but also sophisticated formative beauty, which represents Korea’s dolmen.

Ganghwa Peace Observatory (강화 평화전망대)The Ganghwa Peace Observatory, which was opened in 2008, is a place from where people can literally see the lives of North Koreans from the closest distance in South Korea. Ganghwa Peace Observatory, located on the civilian access control line, consists of wish for unity building, an exhibition room related to war materials, a view room for North Korea, and an outdoor observation deck. There is a place to serve ancestors outside the building so that the separated families with their hometowns in North Korea can hold ancestral rites while looking toward their hometown.
